I have a Salsa Cutthroat (the bike in the pic above), which is marketed as a drop bar mtb due to the mtb hub and bottom bracket spacing, frame geometry designed to have the option for suspension forks, and clearance for mtb tires. It has the woodchipper bars as well. I also have a Transition Spur, which isn't too far off from your Norco Revolver.
If you are thinking about keeping the rest of the Revolver set up as a mtb but then adding the hybrid bars, I think you will lose as much or more riding singletrack (unless its' really buff/ smooth greens and blues) as you gain in efficiency on the road sections. My Cutthroat can be fun on singletrack when I have xc mtb tires on it, but only if the singletrack is really non-technical. It's not that I couldn't ride somewhat chunkier trails set up this way, but it wouldn't be any fun. Sure, having full suspension would make it more capable, but I really don't like the drop bar setup for anything technical. Any setup is a compromise, for sure, but I would rather ride the road transfers a little bit slower and then have full fun on the singletrack.
The solution I went to was to get another set of wheels for the Spur and set them up with light xc tires. On rides where I prioritize efficiency over grip, I ride with the light/ fast setup; on days when I need grip to keep me out of the hospital, I ride the burlier setup. On days when there is only a little bit of trail and a lot of smooth dirt road, I ride the Cutthroat. If I had to go back to one bike, it would be the Spur with two sets of wheels. No drop bars, no Cutthroat. Who only wants one bike, though? N+1.
Ultimately it depends on which end of the ride spectrum you prioritize- dirt road efficiency or trail capability. Survive the road to ride trails, or survive the trails to ride the roads. I don't think I would be happy with the hybrid bars on a mtb on trails.
I completed the Leadville Trail 100 race in '22, and it is mostly dirt road- some smooth and fast, but also a lot of pretty chunky jeep track. There was almost nobody doing it on a gravel bike despite this, and all the professionals were on xc mtb's. Personally, I would never try it on drop bars, regardless of what they were connected to.

Prepping for next year’s longer trips, I ordered an Old Man Mountain Elkhorn axle-mounted rear rack then one turned up on FB Marketplace locally at a great price so now I have front and rear! Looked at Tailfin (too expensive) and Aeroe (stay mounted, not risking with my CF frame) but the OMM stuff won out.
